Cardigan Castle, or Aberteifi, has been so much transformed by the incorporation of the keep into a modern house that nothing decisive can be said about its original plan, but there is nothing to foreclose the idea of a previous motte, and Speed’s plan of 1611 seems to show that the keep and the small ward attached to it were on a higher elevation than the bailey. That the first castle was a wooden one is rendered almost certain by the fact that Rhys ap Griffith, after having demolished the previous castle, rebuilt it with stone and mortar, in the reign of Henry II.[922] The Welsh chronicler speaks of this castle as the key of all Wales, an exaggeration certainly, but it was undoubtedly the most important stronghold of South Ceredigion. [H. W.]

Cilgerran, or Dingeraint ([Fig. 41]).—This castle was certainly built by Earl Roger;[923] a castle of great importance, in a magnificent situation. Like nearly all the castles in our Welsh list, it was repeatedly taken by the Welsh and retaken from them. The present masonry is of the 13th century, but the original motte-and-bailey plan is quite discernible. [H. W.] It was a connecting link between the castles of Pembrokeshire and those of Cardigan, and stands near a road leading directly from Tenby and Narberth to Cardigan.

Aberystwyth, also Lampadarn Vaur, also Aberrheiddiol.[924] In 1109 Henry I. deposed Cadwgan, a Welsh prince who had purchased from the king the government of Cardigan, and gave that country to Gilbert, son of Richard, Earl of Clare, who took possession, and built a castle “opposite to Llanbadarn, near the mouth of the river Ystwyth.”[925] This was undoubtedly the precursor of the modern castle of Aberystwyth, but it is doubtful whether it was on the same site; the present ruins are not opposite Llanbadarn. The castle was as important for the defence of N. Cardigan as Cardigan Castle for the south. It was taken at least seven times by the Welsh, and burnt at least five times. The present ruins are not earlier than the time of Edward I., and there is no motte or keep. [H. W.]

*Blaenporth, or Castell Gwythan ([Fig. 41]).—Also built by Gilbert de Clare, and evidently placed to defend the main road from Cardigan to Aberystwyth. The motte and bailey are still remarkably perfect, as shown by the 25-inch Ordnance Map.

Ystrad Peithyll.—Another of Gilbert de Clare’s castles, as it was inhabited by his steward. It was burnt by the Welsh in 1115,[926] and is never mentioned again, but its motte and ditch still survive, with some signs of a bailey, close to the little stream of the Peithyll, near Aberystwyth. [H. W.]

Chastell Gwalter, or Llanfihangel, in Pengwern ([Fig. 41]).—Castle of Walter de Bec, probably one of the barons of Gilbert de Clare. First mentioned in 1137, when it was burned by the Welsh.[927] There is a small but well-made motte and part of an adjoining bailey standing in a most commanding position on a high plateau. The ditch of the motte is excavated in the rock. [D. H. M.]
